PAT NT OFF- on. A

PROCESS OF PRODUCING SODIUM PEROXID.

SPECIFICATION formingpart of Letters Patent N 0. 739,375, datedSeptember 22, 1903. Application filed December 12, 1902. Serial No.134,988. (No specimens.)

United States, residing at Cleveland, in the county of Ouyahoga andState of Ohio, have invented certain new and useful Improve-v ments inProcesses of Producing Sodium Peroxid, of which the following is aspecification.

This process is intended for the rapid and complete conversion of sodiuminto its per-v oxid.

The process is distinguished from those heretofore proposed or incommercial use by the fact that the metallic sodium ismaintainedinafiuid-that is,a liquidor gaseouscondition and by thethorough admixture of the fluid sodium and oxidizing agent, which isusually air.

The generic process may be carried out in two specifically differentways, as follows:

First. The sodium is melted and a stream or streams of air are blownthrough it from a pipe or finely-perforated nozzle. Instead of air,oxygen,steam, or other gaseous or solid oxidizing agent may be injectedor distributed through the body of molten sodium.

Second. The sodium is heated to a temperature sufficient to vaporize it,and the sodium vapor is thoroughly intermingled with air or otheroxidizing agent. The sodium is thus oxidized with great .rapidity andits peroxid precipitates to the bottom of the chamber in which thereaction is efiected.

It will be seen that this process is a much quicker and more economicalone than that in common use, in which lumps of solid so-' dium areheated and a current of air is passed in contact with their surfaceonly.

In practicing our process an excess of oxidizing agent is necessaril emloyed, since otherwise the whdlefwd ibm'ill'not be converted toperoxidomThe a fbT-bther oxidizing agent is preferablycarefuIIy'd'r-i'ed before beijifgbrought into the-presence ot thesodium.

We claim- 1. The process of producing sodium peroxid, which consists inbringing sodium into a fluid condition and intermingling an oxiw dizin'gagent therewith in excess, as set forth.

2. The process of' producing sodium peroxid, which consistsin bringingsodium into a fluid condition and intermingling a gaseous oxidizingagent therewith in excess, as set forth.

3. The process of producing sodium peroxid, which consists in bringingsodium into a fluid condition and intermingling air therewith in excess,as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
